The radiation doses due to X-ray radiation of 26 diagnostic installations in Dhaka city have been measured using thermoluminescence dosimeter (TLD-100) and portable dose rate meter. General information about every installation has been recorded. Measurements have been carried out for patient's entrance skin dose levels for various types of X-ray projections and for dose rates at some specific locations (e.g., control panel,
inside and outside of the door). The organ and effective doses have been estimated by using a computer program PREPARES. Doses for six organs for female and four organs for male patients have been estimated using this program. The present measurements will provide a useful baseline for future measurements and will be used to evaluate the collective doses to the population from medical exposures and the radiation risks from the various radiological procedures.
